Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between the solubility of a substance and temperature.

Front

What does it mean if a solution is saturated?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature.

Front

How does temperature affect solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.
